JOHN BEAN, OF LOS GATOS, CALIFORNIA.

SPRAYlNG-PUMP.

To aZZ whom it may concern:

Be it known that 1, JOHN BEAN, a citizen of the United States, residing; at Los Gatos, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Spraying-Pumps, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to an improvement in insectilespray-pnmps, and is especially adapted for the use of Vintners, fruit-growers, nurserymen, gardeners, &c., and is designed to force the destructive liquid through a suitable hose and insectilespray-nozzle, for the purpose of destroying troublesome insects that infest fruit-trees, vines, &c. This instrument is designed to be carried about from place and used at the convenience of the operator; but it is also adapted to be submerged and operated in a large cask,when necessary to employ a large quantity of liquid.

The object of my invention is to provide an insectile spray-pump that is adapted to both mix and eject the destructive liquid, and one that is susceptible of high pressure, and having means of increasing either the atmospheric pressure or the quantity of liquid, as may be required, and which is adapted either as an air-pump or as a liquid-pump, and which will also serve to perform both functions at the same time.

The construction and operation of my improvement will be more readily understood by reference to the accompanying drawings, which are made a part of this specification.

Figure 1 represents a vertical sectional view of the instrument with discharge-pipe, hose, and nozzle attached. Fig. 2 is a top View with the hose removed and a slight portion of the top broken away. Fig. 3 is an inverted plan view of the valve and spring; and Fig. 4, a side view of a portion of the plunger-rod, showing the flap which closes the orifice-valve.

A designates the receivingbasin, which is adapted to receive the liquid that is to be pumped into the main receptacle or chamber B.

D designates the pump-stock or plungercase; G, the plunger rod or pipe; d, the plunger; E, plunger-valve;f, lower or outlet valve; 9, escape-cock; h, air-cock; I, discharge; k,

lead pipe or hose; Z, stay-rod; m, spray-nozzle; a, fluid-valve; 0, convex bottom of chamber B; P, bottom of receiving-basin and upper head of chamber B; r, valve-spring.

Like letters denote like parts throughout.

The upper end of the pump is firmly secured to the bottom of the receiving-basin A, and extends down into the receptacle or liquid and air chamber, B, with its lower end near the bottom of the chamber. The pump is open at the top and adapted to receive the liquid from the receiving-basin A. The plunger-rod O is composed of a tube, and is provided with a valve, n, located near the lower end and in close proximity to the plunger. Near the top of the plunger-rod C an air-cock, h, is inserted, and is adapted to admit air into the hollow plunger-rod.

\Vhen the operator is desirous of charging the instrument preparatory for use, he fills the receiving-basin A with the liquid preparation. The top of the pump being adapted to receive the liquid it passes down and fills the pumpstock or plungercase D. At the upward movement of the plunger the fluid enters valve it, passes down through the center of the plunger and through valve E into the lower part of case D. The air-cock h, near the top of the plunger-rod, being open permits the air to enter, and passing down the tube mingles with the liquid, and passes with it down into the lower part of case D. At the downward stroke of the plunger,valve E is closed, and the liquid and air are forced out through valvef into the retaining receptacle or chamber B. The lower end of the pump being near the bottom of chamber B, the liquid and air are thus forced into the chamber at the bottom, thereby serving to thoroughly stir and mix the liquid, the air passing up through it. Valves E andf both open downward and outward, and are held in proper position by a suitable spring, 1', as shown in Fig. 3. When the plunger is moved npward,valvef is closed by the pressure of the liquid and air in chamber B at the same time valve E is opened, valve 11 being also open, the liquid and air are permitted to pass down into case D, as has been described.

\Vhen it is desired to increase the quantity of liquid in chamberB beyond what the pressure of the air will admit of, we open the cscape-cock g, and permit the air to escape, I

the air-chamber to force out all the liquidyor when a greater air-pressure is desired-forthe purpose of forcing the liquid .out of the spraynozzle with greater force, we close'the valve n in the lower part of the plunger-rod, thereby preventing the liquid from entering'and passing down through the plunger. We then openair-cock h, which admits airinto the hollow plunger-rod. Then when the plunger is operatedthe pump acts as an air-pump only, 1 and forces air int-o theinstrument to the :desired extent to either force the liquid .allout depth of the vessel. The process of pumping is then performed in the same manner as before.

The stay-rodl is securely fastened to the convex bottom 0 of chamber B and to the top Paiso, thus serving to'hold the two heads to gether .and preventing any liability of-forcing the heads out under a heavy pressure. The

' discharge-pipe Iis fastened to the upper head,

P, and extends down into the chamber B nearly to the bottom. The lower end of the pipe being open, it is adapted to receive the liquid from near thebottom of the chamber; consequently the air-pressure in the instrument will force all the liquid (or very nearlyso) out 45 through the lead hose and nozzle. I

The nozzle is provided (with thefinecessary means to properly ejectthe liquid in an =.efficient manner, for the purpose of destroying the insectsthat infest fruit and othertrees, vines, shrubs, 1&0.

Plunger-valve E and outer valve, f, are pro vided with a spring, 1', suitable for holding them in position and to insure prompt and proper action.

The flap n serves to close the valve or valveorifice n, when desired, and is pivoted upon a stud, 0,-so astoswing round either way and over the said orifice.

Having: thus described my invention, what I claim,is

1. In a combined liquid and pneumatic in- .sectile pump, the combination, with a suitable receiving-vessel and a charge-receptacle,

' of a pump-stock in communication with said vessel and said receptacle,aplunger-r0d adapted to act upon the liquid to transmit it from the one to the other, and having communi'cation with the stock, whereby air may be introduced simultaneously into the receptacle with the liquid, and a suitable ejecting-tube and sprayer.

2. In an insectile spray-pump, the hollow plunger-rod provided with an external air,- valve located above and outside the pumpstock or plunger-case and an internal valve or gate located within the plunger-case and above the plunger, substantially as set forth;

3. In an insectile spray-;pump,'the combination, with the receiving-vessel and the chargereceptacle, of the pump-stock communicating with said vessel and extending into said receptacleand having an outwardly-opening valve, and the plunger communicating with the stock and having an outwardly-opening valve, the discharge-pipe, thehose, and the spraynozzle. 4." In liqnid'insectile pump,'the combination, with a-suitable receiving-vessel and a charge-receptacle, of a pumpstock in conimunication with said vessel andsaid-receptacle, aplunger-rod adapted to act upon the liquid to transmit it from the one to the other and having communication with the stock, and

a suitable ejectingtube and sprayer.

In testimony whereof I aifix mysignature in presence of two witnesses. I JOHN BEAN.
